Definitions
- the present invention relates to a method for exchange of information in a network using the protocol Internet (IP).
- IP protocol Internet
- the Internet protocol is a protocol network layer which is among others the object of the technical report RFC 791 of the Internet Community (or IETF "Internet Engineering Task Force").
- information is transmitted in the form of datagrams with a header in which include, inter alia, control parameters, routing parameters and addressing parameters (IP addresses) that allow information to be routed between two network devices.
- the parameters of routing are contained in a service type field (more known as the TOS field for "type of service") defined in particular in technical reports RFC 1349 and RFC 1455 that specify the size of this field and the nature routing parameters (priority, reliability, quality ...) .
- the Internet protocol There are planes with internal networks using the Internet protocol. These networks include a public network of servers used in particular by the crew to get information on the flight or passengers, on borrowed airports ... and to allow passengers to access entertainment and a secure network used for operation of the plane itself.
- the public network is weak secure and is connected to the secure network via a protection and routing device.
- the public network can also be connected by a device classic routing to the Internet.
- the protection and routing device is able to transmit datagrams from the network unsecured only if he is able to identify the server that issued the datagram and that this server is well one of the servers embedded on the plane.
- An object of the invention is to propose a method exchange of information by Internet protocol under form of datagrams including a service type field normally dedicated to receiving routing parameters, information circulating in a network including equipment of a first type and at least one equipment of a second type, the process allowing the equipment of the second type to identify in a simple way the equipment of the first type having issued a datagram in its direction.
- the identifiers are associated with the equipment of the first type based eg tasks performed by that equipment or their locations in the network. The identifier then allows the equipment of the second type of determining whether he is allowed to receive and transmit datagrams from a device of the first type whatever the IP addresses and MAC of this equipment.
- the identification zone comprises at least one normally unused bit in the standard field of service.
- the method includes the step of, upon receipt by the device of routing a datagram from the external network, code an unauthorized identifier in the bits of the field type of service that correspond to the area Identification.
- the datagrams coming from the external network include an unauthorized identifier so that they are rejected by the equipment of the second type.
- the method comprises the step of distributing equipment of the first type according to groups each comprising at least one of the equipment of the first type, the identifiers being associated with the groups.
- the distribution of equipment of the first type according to groups is particularly interesting when the number of equipment of the first type is greater than number of identifiers that can be coded in the zone identification of the service type field. Divide equipment of the first type according to groups and affect an identifier for each group then makes it possible to reduce the number of identifiers needed.
- the method of the invention is here described in relation to a network generally designated in 1 boarded for example aboard a plane.
- the network 1 comprises a network 2 of servers 3.a at 3.f and a secure network 4 connected to the network 2 by a protection and routing device 5.
- the device protection and routing 5 is known in itself and includes a router associated with a filter element of DMZ type (for "demilitarized zone").
- Network 2 is less secure than the secure network 4.
- the network 2 is further connected by a router 6 to an external network, here the Internet network 7.
- an external network here the Internet network 7.
- IP Internet Protocol
- the method of the invention comprises the step of distributing servers 3.a to 3.f according to three groups 8.
- the group 8.a includes servers 3.a, 3.b, group 8.b the servers 3.c, 3.d and the group 8.c the servers 3.e, 3.f.
- each group 8.a, 8.b, 8.c is associated a identifier encoded on two bits, namely 01, 11 and 10 respectively.
- Servers 3.a through 3.c are configured to set in the service type field of the IP datagram a identification area comprising the last two bits of this field (the last being a bit usually not used).
- a table of authorized identifiers is stored in the protection and routing device 5.
- the identifier 01 of the group 8.a to which the server 3.a is attached is coded in the identification area datagram service type field.
- the datagram is directed to the device of protection and routing 5.
- the identifier Upon receipt of the datagram by the device protection and routing 5, the identifier is read and the protection and routing device 5 is configured to verify that the identifier is in the table of authorized identifiers.
- the datagram is accepted and transmitted to the secure network 4. Otherwise, the datagram is discarded.
- the router 6 When receiving a datagram from the network Internet 7, the router 6 is configured to encode a unauthorized identifier in the bits of the type field of service that correspond to the identification area (that is, the last two bits of this field). In the occurrence, the router 6 sets these bits to zero. So, no datagram from the Internet 7 can be routed to the network 4.
- Network 2 can understand a different number of servers and / or other equipment, and the number of groups may be different depending on the number of servers or more generally network equipment 2 and the number of bits used for the identification field of the service type field. This number of bits may be different from two and limited only by the size of the service type field.
- the number of equipment attached to groups may vary from one group to another.
- network 1 may be more complex.
- Networks 2 and 4 can be connected to each other by through two protective devices and routing connected selectively, possibly in alternation, to network 4 and two routing devices each connected to the two protection devices and 2. This arrangement makes it possible to arrange a backup routing device in the event of a failure from one of the two routing devices.

Abstract
Description
- configurer les équipements du réseau pour définir dans le champ type de service une zone d'identification,
- associer aux équipements du premier type des identifiants codables dans la zone d'identification du champ type de service,
- dans l'équipement du deuxième type, mémoriser une table d'identifiants autorisés,
- lors de l'émission d'un datagramme par un des équipements du premier type vers l'équipement du deuxième type, coder dans la zone d'identification l'identifiant de l'équipement du premier type concerné et, à la réception du datagramme par l'équipement du deuxième type, lire l'identifiant et vérifier qu'il figure dans la table des identifiants autorisés avant d'accepter le datagramme.
